This is an important book but hard to find. It's out of print, costs hundreds of dollars for merely "fair quality" used version, and the Kindle edition is unreadable due to formatting errors.
I'm not a legal expert, but I think the copyright is expired. I found a PDF version online and fixed up some of the formatting. I think the following is a reasonable version to read.
